Abstract - As the 5 th part of the serial studies on the genus Lecithocera Herrich-Schäffer of Thailand, nine additional species including six new species: L. gilviana sp. nov., L. orbiculata sp. nov., L. tumidosa sp. nov., L. calomerida sp. nov., L. poculata sp. nov., and L. eremiodes sp. nov., are reported in this paper. Three species, L. mylitacha Herrich-Schäffer, L. castanoma Wu, and L. squalida Gozmány, are first reported from Thailand, and the females of them are newly found since the species were described. Images of adults, venation, and the male and female genitalia of the known species are given. Key words: Taxonomy, Lecithocera, Lecithocerinae, Gelechioidea, morphology, description. INTRODUCTION Lecithocera Herrich-Schäffer (Lecithoceridae: Lecithocerinae) is the largest genus of the family, and includes more than 300 species worldwide. Since Gozmány (1978) reviewed 46 Palaearctic species of the genus, including the northern border of the Oriental Region, additional papers have been subsequently published for the fauna of China (Wu, 1994, 1997; Wu et Liu, 1993), Taiwan (Park, 1999, 2000), Sri Lanka (Wu and Park, 1999), and the Korean peninsula (Park & Lee, 1999). In the recent studies for the genus Lecithocera of Thailand, 16 species including 10 new ones were reported by Park (2005, 2006a-b, 2009). In this 5 th part of the study for the genus Lecithocera, we report nine species including six new species. These species are externally similar by the small size with less than 14 mm of the wingspan and the orange-white to pale brownish-orange forewing with conspicuous blackish discal stigmata. In the early days, Patouissa Walke had been synonymized with Lecithocera by Meyrick (1910). Gozmány (1978) divided Lecithocera into two subgenera, Patouissa and Lecithocera, based on the hindwing venation with M 3 stalked or coincident. Wu (1997) followed this classification in his revision of the Chinese Lecithoceridae. Of the species presented here, the first seven species (numbers 1 to 7) belong to the subgenus Patouissa Walker and the last two species (numbers 8, 9) to the subgenus Lecithocera, according to Gozmány s classification. MATERIALS AND METHODS Material examined is based mainly on loaned specimens from the Osaka Prefecture University (OPU), Japan, which were collected by Japanese microlepidopterists during expeditions in 1981, 1985, and The wingspan was measured from the left to right forewing apex. For the descriptions of new species, color terms follow Kornerup and Wanscher (1978). Types will be deposited in the OPU, Japan, on an indefinite loan from Thailand and some types will be in the McGuire Center for Lepidoptera and Biodiversity, Florida Museum of Natural History, University of Florida, Gainesville, USA.

This species is externally similar to L. castanoma Wu & Liu, but differs by the orange-white ground color of the forewing with vein R 3 free from R 4+5 and the hindwing with M 3 stalked. The male genitalia are similar to those of L. ambona and L. eligmosa Wu & Liu, but differ by the less slender basal lobes of the uncus and the convave, U-shaped caudal margin of the juxta. Description. Male. Wingspan, 11.5 mm. Head with an orange-gray dorsomedian line, with orange-white erect scales laterally. Scape of antenna moderate, orange white dorsally, not ciliate; flagellum pale orange, paler toward apex, slightly thickened for basal 1/3, with inconspicuous annulations.

Tegumen and thorax pale orange. Forewing narrow, elongate, with acute apex; ground color orange white to orange gray, irregularly scattered brownish scales beyond 2/3 length of wing; a short, black subbasal streak present; a dark-brown discal spot at middle and another at end of cell, and similar plical dots below them; costa nearly straight, with blackish streak along margin at basal 1/5; apex more or less acute; termen slightly concave medially; fringe unicolorous, speckled with brownish scales near apex; venation (Fig. 13) with R 1 arising before middle of cell; distance between R 1 and R 2 longer than that between R 2 and R 3 ; R 3 connate with R 4+5 ; R 4 stalked for nearly 3/5 length; R 5 to termen; M 2 nearly parallel to M 1 ; M 3 free; CuA 1 stalked for short distance; cell weakly closed. Hindwing pale gray to whitish, broad; Rs and M 1 short-stalked; M 3 stalked for 2/5 length; apex acute; termen slightly concave medially; cell closed with weak cross vein. Hind tibia slender, with rough orange-white scales dorsally. Female unknown. Male genitalia (Figs. 22, 22a-b). Basal lobes of uncus elongate, directed outwardly; caudal margin broadly V-shaped. Gnathos slender, bent preapically. Valva with costal bar heavily sclerotized, angled medially, broad basally; cucullus elongate, tapered toward apex, with nearly straight costa; apex narrowly rounded, as long as basal part of valva, bearing broad scales apically, with bristles on basal half of ventral margin. Caudal margin of juxta U-shaped. Aedeagus stout, gently curved, broad basally, with a short apical spine; cornuti consisting of two clusters of spines near base: one long and another much shorter; a long heavily sclerotized, curved rod, zigzaged at middle and strongly curved at both ends, and a long sac containing densely spinous spicules with a heavily sclerotized plate on ventral surface. Distribution. Thailand (Kanchanaburi). Etymology. This species name is derived from the Greek, eremos (= lonely, solitary) with the Greek suffix, -odes, denoting resemblance. DISCUSSION The genus Lecithocera Herrich-Schäffer has been characterized by the wing venation with CuA 1 stalked in the forewing; M 2 present, and M 3 stalked or coincident in the hindwing; normally thickened 2 nd segment and slender 3 rd segment of labial palpus; the male genitalia with an elongate valve; and the specialized abdominal sclerite between the 7 th and 8 th segments with well-developed hair pencils. As Park (1999, 2000) noted, some related genera that have been separated by the difference in venation (Walker, 1864; Meyrick, 1904; Gozmány, 1978) should be reconsidered for their generic status and be re-defined using recent techniques such as DNA sequence analysis. Considerable variation in wing venation is often found within the genus. For this reason, Park(1999) treated Patuoissa Walker to a synonym with Lecithocera as Meyrick (1910) did. Additional examples of variable venation are shown by L. orbiculata sp. nov. with R 5 absent in the forewing, L. squalida Gozmány and L. eremiodes sp. nov. with R 3 free from R 4+5, and L. poculata sp. nov. with CuA 1 free in the forewing. No distinct, separable characters are found in male genital structures among species of the Patouissa-group (species No. 1-7 in this article) and Lecithocer-group (species No. 8-9) as classified by Gozmány (1978). Meyrick (1904) described the genus Sarisophora, based on the type species, S. leptoglypta Meyrick from Queensland, distinguishing it from Macrotona Meyrick, which currently is a junior synonym of Lecithocera, by the absence of M 2 of the hindwing. In fact, the vein referred as M 3 in his description is M 2, and M 3 is coincident with CuA 1. There is no difference between Patouissa and Sarisophora in venation. This will be discussed in a following article. Without doubt, all species described in this study belong to Lecithocera, based on the combination of characters of the venation and the male genitalia.
